The Schedule referred toxin these Letters Patent and making".part of the same.

T0 all 'whom "it may concern:

B'e it known that I, CHARLES PABKR, of Meriden,

vin the county of New Haven, and State of `Gonnecti cut, have invented a new Improvement iu' Auxiliary J'aws for Vises, and `I do hereby declare the follow-j ing, when taken in connection withthe accompanying drawings, and the letters of reference marked thereon,

- to be-a full, clear, and description of the same,;and .which said drawings' constitute. part of this specification, and represent,'in

Figures 1 and 2, end views of the two jaws; Figures 3 and 4, top views of the same; `Figures and 6, front and rear views, respectively;

. `and in Eigures 7 andfS, central sections.

' 4This invention relates toan i1nprovemeut for at tachment to the jaws of vises, in order that the same jaws may serve for; giiping cylindrical articles, as pipe, c., and consists in the construction of an auxiliary jaw, to` set on over each` of the principal jaws'of a v vise, and the two auxiliary jaws formed so.that the V*central part of `one will project and enter into a corres'pondingicentral reeess on the other auxiliary jaw,

andthe two jaws cut out on their meeting-surfaces at lnearly. an angle of forty-five. degrees,- both .l upon the upper and-,lower edgeto'ward the centre.'

. Toenable `others skilledin the art'to make and use, my invention, I willproceed to'describe the same as illustrated in the accompanying drawings.

' A represents one auxiliary jaw, B, theother, rmed asf seen iu' the several figures,l so. that each of the auxiliary jaws will s etrespectively over the jaws of a vise,

ayseen in figs 7, and 8, the jaws of the vise being denotedin broken lines.

Upon-the inside of one bf the auxiliary jaws A, I i -form or attach two cheeksfO, projecting from the auxiliary jaw inward, the' inner edge of the said cheek formed as seen in figs. land 7, that is, cut back from the upper and lower edge at an angle of about fortyve degrees. f' Upon the other auxiliary jaw B, I form or attach a, single cheek, D, in such relative position lto the two cheeks' O, upon the other auxiliary jaw, that the cheek AD will pass between the twocheeks O O, as seen lin figs. 2 and 4. i

The edge of the cheek D is cut back in like manner as the cheek C, as seen in figs. 2 and '8, sothat as the two auxiliary jaws upon theirrespective principal` jaws are forced together, as -seen in figs. 7 and 8, they will grasp whatever is placed between them, and especially adapted for grasping pipe and like. cylindrical articles. j I d o not wish to be `understood to claim, asl my invention, 'the arrangement of' the jaws so thgtfoue will 'pass'between thetwo opposite jaws, as such, I am aware, is very old; but

What'ldo claim, and desire to 4secure by Letters iS--f 4 l Theauxiliary' jaws A and B .providedV respectively' witl1 the cheeks- O and D, all constructed and applied to Ithefjawsof avise, substantially as described and in the manner set forth.
